To all whom it may concern:

' come these difficulties, and to provide a con- Be it known that I, BEHR MANIsoHEWITz,

struction in which exact equality of speed a citizen of the United States, residing in the I may be maintained between the two carcity of Cincinnati, in the county of Hamilriages by means of that certain novel conton and State of Ohio, have invented certain I struction to be hereinafter described and new and useful Improvements in Mechanism pointed out in the claim, the essential feafor Regulating the Speed Between Traveling ture of which consists in coupling together a Carriers, of which the following is a full, pair of variable speed devices, through one of clear, and exact description, reference being which the speed of the cracker machine is had to the accom anying drawings, forming l regulated, and which variable speed device part of this speci' cation. l also drives a second variable speed device, My invention has special relation to the through which the oven transfer mechanism regulation of the speed of traveling belts and is driven. the like, so that one belt can transfer its load In the drawings Figure 1 is a side elevation to the other without disturbing in the least of a portion of the cracker cutting machine, degree the position of the load, and my inand a portion of the oven with its traveling vention has particularly to do with the transbelt, showing the two speed devices and the fer of the cut dough for crackers, bakery mechanism for connecting and regulating the goods, and the like, fromthe delivery apron speed thereof.

These ovens are sixtyous mechanisms directly under each other. five or seventy feet long, and the goods pass- As the invention relates more particuing slowly through the oven are baked when larly to the coupling together of the several delivered at the far end of the oven. If it variable speed devices, the particular conwere possible to drive by ordinary means, the l struction of cracker cutting machine, or oven carriage at the same rate of speed as the oven, and the particular construction of the delivery apron of the cracker cutting mavariable speed devices, is not of particular chine, the goods would be transferred or deconsequence, I have not illustrated in the livered from the machine to the oven belt drawings any details of these various parts. without manual interference, but it has been In the drawings 3 illustrates the side found impossible with the ordinary gearing standards of any construction of cracker to connect the two mechanisms, so that one machine, with its rolls 4-4 and train of will travel at exactly thesame rate of speed gears 55, and with a delivery apron 6, as the other. As a result, when the two maupon which the crackers are delivered. from chines have been geared or otherwise conthe machine. Located immediately under nected, the oven belt is found to travel this delivery end of the machine, is the traveling wire frame or apron 7, provided with sprocket chains 88 on each edge, which comprises an endless apron carried 'by the sprocket wheels 9, 10, 11 and 12 It will be understood that the sprocket wheels 9 and 10 are some sixty-five or seventy feet apart.

so that it becomes impracticable to connect The driving mechanism which I have prothe two devices by any train of gearing or vided for driving this endless oven, consists pulleys that will accomplish the result deof the driving shaft 13, with a drivingpulley sired. i 14,which shaft 13 carries the beveled gear 15 It is the purpose of my invention to overmeshing with the beveled gear 7 16 on the slightly slower, or slightly faster, than the delivery mechanism of the cracker machine, and the goods are either bunched on the apron, or spread too far apart. 'Any slight error in the equality of speed is greatly exaggerated owing to thelength of the oven belt,

counter-shaft 17, which carries the sprocket wheel 18, driving by sprocket wheel 19 the worm gear 20, which meshes with the gear 21 on the shaft of the sprocket wheel 10.

For the cracker machine 22 is the driving shaft which carries the sprocket wheel 23 driven by the sprocket chain 24. This sprocket chain 24 is driven by the sprocket shaft 25, which is connected with any desired construction of variable speed device. The one I have illustrated is of ordinary construction, and comprises a framework 26, in which the shaft 25 is journaled, and this shaft carries one pair of coned spools 27-27, with the belt 28 therefor running over a second pair of coned spools 2929, mounted on the shaft 30 journaled in the frame. Both pairs of coned spools slide on feathered shaft Keys, and these coned spools are expanded or contracted by a pair of levers 3131 fulcrumed centrally at 3232 between the two shafts 25 and 30, and connected to the spool hubs. The operating ends of these levers 31 are pivoted on nuts 33-33 on the right and left hand screw 34, also j'ournaled in the frame, so that the rotation of the screw 34 will expand and contract the sliding spools to maintain the proper belt tension at the same time that the rate of speed transmission between the shaft 30 and the shaft 25 is varied. The shaft 30 is driven by the belt 35 and pulley 36 on the shaft 30 from any suitable power. Mounted on the shaft 25 is the pulley 37, which drives by belt 38 the pulley 39 on the shaft 40, which is journaled in a second variable speed device frame 41. This second variable speed device is a counterpart of the one just described. The shafts 40 and 42 carry the coned spools 4344 with key and feather for the spools to permit them to slide on these shafts. 45 is the connecting belt, 46*46 the operating levers for the spools fulcrumed at 47 47, and the outer ends of these levers are pivoted to the nuts 4848 on the right and left screw threaded shaft 49, so that the rotation of the shaft 49 will adjust the cones to vary the transmission speed in the shafts 40 and 42. The shaft 42 pulley 50, over which runs the belt 51, by which the driving oven traveling belt is operated. For regulating the speed of these two variable speed devices, I connect by sprocket wheels and chains 51-52 the screw shaft 34 with the sprocket 53, coupled to the worm 54, which engages the gear 55, operating the dial indicator 56. This worm 54 is actuated by the hand crank 5'7, so that the train of sprocket chains and wheels may be turned to thus vary the speed rotate the shaft 34, and

of the driving mechanism of the cracker machine, the dial 58 and pointer 56 indicating the speed. In the same way the right and left screw shaft 49 is rotated by the train of sprocket wheels and chains 5859, and for this operating device, 60 is the hand crank, 61 the dial, and 62 the pointer. In the transmission of the rotation of these hand dials in each case idler sprockets 63-63 and 6464 are employed.

In making use of the devices above described, the variable device for the cracker machine is set to obtain any desired speed for the apron 6, and the delivery of the cut cracker dough from the machine. The cracker machine is then started, and with the hand crank 60, the operator regulates the speed of travel for the oven belt 8, so that the oven belt will travel at the exact speed. delivery of the cracker machine. Then, as the necessity of the case may require, according to the heat of the oven and the character of the fire, the operator.regulates the speed through the oven by the hand crank 57, which as will be understood, alters the speed of the cracker machine.

It is essential to have the two speed de vices, the speed device for the cracker machine driving the speed device for the oven machine, in order that the speed delivery of the two machines may be regulated exactly, but when once regulated, except for lost motion, and wear, etc., the oven sqeed device does not need to be touched, and the operator simply regulates the oven speed by vary ing the speed of the cracker machine.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a mechanism of the class described, the combination with a cracker machine for cutting dough for bakery goods provided with a delivery apron to deliver the cut material from the machine, and an independent oven conveyer comprising an endless traveling frame for carrying the goods through the oven of a variable speed device for regulating the speed of the delivery apron, and a second variable speed device for regulating the speed of the oven conveyor, intermediate mechanism connecting the two speed devices, means for driving the delivery apron variable speed device, and independent mechanism for regulating the speed of each of the two speed devices.
